To find out the circumference of a circle, you have to multiply the diameter of the circle with pi.(3.14)
First, to get the diameter of a circle you have to multiply the radius by 2.

The diameter is 20 centimeters.
Then, multiply the diameter by pi.(3.14)

The circumference is 62.8 centimeters.
To solve for x we proceed as follows:
from the laws of logarithm, given that:
log_a b=c
then
a^c=b
applying the rationale to our question we shall have:
log_5 x=4
hence
5^4=x
x=625
Answer: x=625
I got 276 as the answer. So D
